[0046] Please refer to Figures 1 to 4 As shown, this utility model provides a bridge structure for a flexible photovoltaic power station. The flexible photovoltaic power station consists of several photovoltaic arrays, each containing several photovoltaic modules. The bridge structure 1 is assembled onto the photovoltaic modules 2 of the flexible photovoltaic power station, and includes a bridge body 10 and a limiting member 11 assembled with the bridge body 10. The bridge body 10 has an integrally formed top wall 101, side walls 103, and bottom wall 104. After the bridge structure is assembled onto the photovoltaic modules, the limiting member 11 at least partially extends into the cavity formed by the top wall 101, side walls 103, and bottom wall 104. The bridge body 10 forms a C-shaped structure. In this application, both the bridge body 10 and the limiting member 11 are metal components.

[0047] In this embodiment, at least two assembly holes 105 are provided at intervals on the bottom wall 104 of the bridge body. In an exemplary embodiment of this application, four assembly holes 105 are provided at equal intervals along the overall length of the bottom wall 104 of the bridge body 10 to meet different application scenarios. The limiting member 11 is provided with through holes (not labeled) corresponding to the assembly holes 105. Fasteners 12 pass through the through holes and the assembly holes 105 to assemble the limiting member 11 and the bridge body 10 together.

[0048] Specifically, in this embodiment, the limiting member 11 includes an assembly portion 110 and an abutment portion 113 formed by bending upward from the assembly portion 110. The abutment portion 113 is connected to the assembly portion 110 via a transition portion 114 and is parallel to the assembly portion 110. The abutment portion 113 and the assembly portion 110 form a receiving channel 115 with a height of 5mm-8mm. Both the assembly portion 110 and the abutment portion 113 have rounded bevels at their ends. After assembly, the end of the abutment portion 113 presses against the frame 21 of the photovoltaic module and abuts against the photovoltaic module to effectively prevent the bridge structure from rotating.

[0049] The through hole is provided on the assembly part 110, and the projection of the end of the abutment part 113 in the vertical direction is located outside the assembly hole 105. On the one hand, the bottom edge of the frame of the photovoltaic module 2 can be completely housed within the space defined by the bottom wall 104 of the bridge body 10 and the end of the limiting member 11, thereby increasing the stability of the bridge structure and the assembly of the photovoltaic module 2.

[0050] In this embodiment, the lateral width of the top wall 101 is smaller than the lateral width of the bottom wall 104. The outer edge of the top wall 101 is an arc-shaped structure, and the inner sidewall of the top wall 101 is provided with continuous corrugated ribs 102. Setting the outer edge of the top wall 101 as an arc-shaped structure can cover the outer edge of the frame of the photovoltaic module 2, enhancing the stability of the assembly between the bridge structure 1 and the photovoltaic module 2. At the same time, providing continuous corrugated ribs 102 on the inner sidewall of the top wall 101 increases the contact surface between the bridge body 10 and the frame 21 of the photovoltaic module, further strengthening the firmness of the assembly.

[0051] The distance between the inner wall surface of the top wall 101 and the inner wall surface of the bottom wall 104 is 30mm-50mm. The distance between the inner wall surface of the top wall 101 and the inner wall surface of the bottom wall 104 can meet the adaptability of the frame of photovoltaic modules of different specifications, and enhance the versatility of the bridge structure 1.

[0052] In this embodiment, the bridge body 10 is disposed on the frame 21 of the photovoltaic module 2, and the distance between the bridge bodies 10 on the frame 21 of any adjacent photovoltaic module 2 is 20mm-40mm. In this application, independently disposing of the bridge structure 1 on any one of the photovoltaic modules 2 ensures that when the flexible support 3 sways in the wind or experiences significant shaking, all photovoltaic modules 2 in the photovoltaic array can move synchronously without being constrained by the rigid bridge structure 1, thus ensuring that the photovoltaic modules 2 are not damaged by other external forces. Maintaining a distance of 20mm-40mm between the bridge bodies 10 on the frame 21 of adjacent photovoltaic modules 2 ensures that the cleaning robot does not get stuck when moving along the photovoltaic array and also avoids interference between adjacent photovoltaic modules 2.

[0053] In the technical solution of this utility model application, each photovoltaic module 2 of the photovoltaic array is fixedly installed to the flexible support 3 by at least two clamps 4. As a preferred embodiment, each photovoltaic module 2 is fixed to the flexible support 3 by four clamps 4, and the clamps 4 are symmetrically arranged on the opposite frame 21 of the photovoltaic module 2.

[0054] Please continue reading. Figures 5 to 7 As shown in this embodiment, the clamp 4 includes a positioning member 41, a support member 42, and a locking member 44 that assembles the two. The positioning member includes a U-shaped body 410 and a first pressure plate 412 disposed on the top of the body 410 and abutting against the frame 21 of the photovoltaic module 2. A second pressure plate 413 is disposed on the vertical wall of the U-shaped body 410. The second pressure plate 413 has a threaded hole 414. A first bolt 43 is assembled into the threaded hole 414 and abuts against the photovoltaic module 2. The second pressure plate 413 extends horizontally outward from the vertical wall of the U-shaped body. The threaded hole 414 is disposed near the outer edge of the second pressure plate 413 to avoid interference with the flexible support 3 during assembly. The first pressure plate 412 and the second pressure plate 413 are arranged parallel to each other, and the horizontal extension length of the first pressure plate 412 is less than the horizontal extension length of the second pressure plate 413. The height of the inner cavity formed vertically by the first pressure plate 412 and the second pressure plate 413 is adapted to the size of the frame 21 of the photovoltaic module 2. The second pressure plate 413 is positioned higher than the bottom of the U-shaped body 410. When the clamp 4 is assembled with the photovoltaic module 2, the outer edge of the first pressure plate 412 is flush with or located behind the outer edge of the frame 21 of the photovoltaic module 2.

[0055] The bottom of the U-shaped main body is provided with two fastening holes 411, which are located on the left and right sides of the center of the bottom of the main body. The support member 42 has a receiving part 420 and ears 421 extending from both sides of the receiving part 420. The ears 421 are provided with mounting holes 422 corresponding to the fastening holes 411. The flexible bracket 3 is received in the receiving part 420. The locking member 44 passes through the mounting holes 422 and the fastening holes 411 to fasten the clamp 4 to the flexible bracket 3.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
